248,63  m/Moms

40-80 µ. Blåt pigment fra HAN-dynastiet (fra 206 f.Kr. til 220 e.Kr.).

Fra Kremer.

Der findes kun få naturlige blå farver i naturen. I landet mellem de to floder ved Ur og Assur findes cobaltmalm. I Ægypten findes ikke cobalt men kun en naturlig forekomst af kobber. Dette førte til fremstilling af ægyptiskblåt. Fremstillingsmetoden til den kinesiske blå fra Han-dynastiet var længe en hemmelighed, men nu er det lykkedes at fremstille en barium-kobber-fritte, der dog er lidt rødligere end den oprindelige.

Intercultural links and trade of painting materials in the Greco-Roman period.

In book. Mural paintings of the Silk Road: cultural exchanges between East and West: proceedings of the 29th Annual International Symposium on the Conservation and Restoration of Cultural Property, National Research Institute for Cultural Properties, Tokyo, January 2006. Yamauchi, Kazuya; Taniguchi, Yoko; and Uno, Tomoko, Editors. Archetype Publications Ltd. (2007), pp. 81-88, [English]. 8 color figs., 1 table, 10 notes, refs. [ISBN 978-1-904982-22-7].

Examines the interactions between Greco-Roman painting materials and techniques and Central Asian influences along the Silk Road during the Hellenistic period. The similarity of painting techniques and pigment fabrication methods along the Silk Road indicate technology transfer. An overview of Greco-Roman wall painting examines the palette of pigments employed and the techniques used, including the use of lime plaster; a table lists known pigments and colorants and their chemical formulas. A detailed discussion of Hanblue and Egyptian blue notes that they are analogous alkali-metal-copper silicate blue pigments, with Hanblue employing barium and Egyptian blue calcium, which suggests a close relationship to glassmaking technology. An intermediate form between Hanblue and Egyptian blue in Iran employed strontium, which suggests that a geographic range of synthetic technology employing local variants was in place. The author discusses cultural transmission and trade of pigments and iconography in detail.
